The MEAN WELL EDR-120-24 is a single-output DIN rail switching power supply rated at 24 VDC, 5 A, and 120 W, designed for installation on TS-35/7.5 or TS-35/15 DIN rails in industrial control panels and similar enclosures. It accepts a universal AC input ranging from 90 VAC to 264 VAC at 47 Hz to 63 Hz, making it suitable for use across a wide range of AC mains voltages. The unit cools by free air convection with no fan, and includes built-in protections for short circuit, overload, over voltage, and over temperature conditions. Every unit undergoes a 100% full load burn-in test prior to shipment and carries a 2-year warranty.
Key Features and Benefits
Universal AC input / Full range (90 VAC to 264 VAC) - Supports a wide range of AC mains voltages without manual switching, simplifying deployment across different facility power standards.
Built-in protections: short circuit, overload, over voltage, and over temperature - Helps safeguard connected equipment and the power supply itself when operating within the manufacturer's stated limits.
Fan-less design - cooling by free air convection - Eliminates moving parts, which may help reduce audible noise and lower maintenance considerations in quiet or dust-prone industrial environments.
Adjustable output voltage: 24 V to 28 V - Allows fine-tuning of output voltage to match the requirements of connected equipment, within the manufacturer's stated adjustment range.
DIN rail mounting compatible with TS-35/7.5 and TS-35/15 - Installs directly onto standard DIN rails commonly found in industrial control panels, supporting straightforward panel integration.
LED indicator for DC OK - Provides a quick visual confirmation of output status without requiring additional test equipment.
Screw terminal block output connector - Supports secure, tool-assisted wiring connections for reliable field installation.
100% full load burn-in test - Each unit is tested at full rated load before shipment, supporting confidence in out-of-box performance.
2-year warranty - Backed by a manufacturer warranty for added purchase confidence.

Customer Questions
What DIN rail sizes is the EDR-120-24 compatible with?
According to the manufacturer datasheet, the EDR-120-24 can be installed on TS-35/7.5 and TS-35/15 DIN rails, which are the most common standard DIN rail profiles used in industrial control panels.
Can the output voltage be adjusted?
Yes. The manufacturer datasheet specifies an output voltage adjustment range of 24 V to 28 V, allowing fine-tuning to match the requirements of connected equipment.
Does the EDR-120-24 work with both 120 VAC and 240 VAC mains?
Yes. The unit accepts a universal full-range AC input from 90 VAC to 264 VAC at 47 Hz to 63 Hz, so it is compatible with both 120 VAC and 240 VAC mains without any manual voltage selection.
Does this power supply require a fan for cooling?
No. The EDR-120-24 cools by free air convection and does not include a fan, which may help reduce audible noise and lower maintenance considerations in the installation environment.
What certifications does the EDR-120-24 carry?
Per the manufacturer datasheet, the EDR-120-24 carries UL 508, TUV EN62368-1, EAC TP TC 004, and BSMI CN514336-1 approvals. Verify that these certifications satisfy the compliance requirements of your specific application and jurisdiction.
Customer Concerns
I need to confirm the unit will fit inside my existing control panel enclosure before ordering.
The EDR-120-24 measures 4.469 inches (L) x 1.575 inches (W) x 4.929 inches (H) (113.5 mm x 40 mm x 125.2 mm) and mounts on a standard TS-35/7.5 or TS-35/15 DIN rail. Verify that your enclosure provides adequate clearance on all sides for the unit dimensions and for unobstructed airflow, as the supply relies on free air convection for cooling.
I am not sure whether 5 A at 24 V is enough for my load.
The EDR-120-24 is rated for a maximum continuous output of 5 A at 24 VDC, for a total rated power of 120 W. Before installing, calculate the total current draw of all connected loads and confirm it does not exceed 5 A. If your load requires more current or wattage, consult the MEAN WELL EDR-120 series datasheet or consider a higher-rated model.
I want to make sure this supply is approved for use in industrial control equipment.
The EDR-120-24 carries a UL 508 listing, which covers industrial control equipment, as confirmed in the manufacturer datasheet. It also carries TUV EN62368-1, EAC TP TC 004, and BSMI CN514336-1 approvals. Always verify that the specific certifications required by your application, installation standard, and jurisdiction are present before installation.
